When using international characters and UTF-8 the function strtoupper 
will not work well. The file scripts/xlpage-utf-8.php a working way to 
capitalize international characters, it may look complicated but you can 
simply copy the part you need:

   $MakePageNamePatterns = array(
       '/[?#].*$/' => '',                     # strip everything after ? 
or #
       "/'/" => '',                           # strip single-quotes
       "/[^$PageNameChars]+/" => ' ',         # convert everything else 
to space
       '/(?<=^| )([a-z])/' => 'cb_toupper',
       '/(?<=^| )([\\xc0-\\xdf].)/' => 'utf8toupper',
       '/ +/' => '_');

I copied this from the latest xlpage-utf-8.php into config.php (after 
including xlpage-utf-8) and changed the last line that strips spaces to 
replace them with an underscore character.

You shouldn't change or define in your config files any other page name 
variable like $PageNameChars, $GroupPattern, $NamePattern, 
$WikiWordPattern if you want your page names to contain international 

Note that this is from a very recent version 2.2.103 or 104; with an 
older version look at the older xlpage-utf-8.php.

Also note, if you change the $MakePageNamePatterns on an existing wiki, 
some links to existing pages may stop working. In the above example, by 
adding a new underscore character, links like [[Documentation Index]] 
and [[DocumentationIndex]] will point to two different pages (for 
example, the PmWiki/ documentation). You should decide if this is

Yes, this fixes this, and also [[les écoles]] (page name "Les_Écoles", 
uppercase accented characters, la classe).
